Wood privacy fence - planning over the top? Alternatives?

My point was to objectify the disturbance in order to define the correction goal. So you describe yourself as very sensitive and that the music might not even be that loud. But maybe it is actually very loud. Then you would have more arguments against the neighbor and wouldn’t condemn yourself like that. In open fields, sound usually dissipates very quickly because reflections are missing. Yes, the bass frequencies, as the most energetic waves, travel further, but at 10m I would actually claim that at normal neighbor-friendly volumes it should no longer be perceived as disturbing, especially indoors.

Maybe it’s not even 10 meters? Could be less, maybe around 5? Unfortunately, I’m not allowed to insert links but I can gladly send you a video via message and you can tell me if you would find it disturbing. There is also a short-address service called "lmy," they use https and have a .de domain, and if you know the code "V1Ljg" you can already listen to some nice neighbor music. :D

I don't know if measuring a value would bring me anything besides costs. ...

Isn't there also an app for the smartphone? No idea if it's any good.

the question is how the bass transmits. A buddy had problems with the bass from the apartment two floors below in his condo. Curiously, the bass was barely noticeable in the apartment in between.

Yes, bass is strange there, the above-mentioned phenomenon is usually due to the wave pattern of the bass. The lower the frequency, the longer the wave, and it can therefore unpleasantly crystallize somewhere else entirely. At unfavorable multiples of the length, several amplitude peaks of the same direction accumulate (standing wave) and that becomes really unpleasant. If a "valley" meets a "peak," cancellation can occur and you ironically hear nothing at all. In the specific case, it could be that the neighbor standing next to the boombox doesn’t perceive anything loud and therefore turns up the bass even more, but you receive double the normal dose due to unfavorable reflections in a standing wave. However, this is not so dramatic in free field (fewer reflections).

Unfortunately, I am not allowed to insert links, but I can gladly send you a video via message and you can tell me if you would find it disturbing.

Then we would all have to calibrate our setups, which doesn’t help much. A reasonably good sound level meter costs around 100 EUR. Or maybe you can rent one somewhere? Just make sure it doesn’t only measure in dB(A) mode (bass filtered out), but can also measure in dB(C) (full spectrum).

Maybe also interesting for the current question?

Thanks, I read through it!

In another forum, it is the pool's water pump that constantly causes disturbance. He managed by nailing old Bundeswehr blankets (those felt blankets that are still lying around somewhere in every authority) behind his wooden privacy fence. Outside, that is, on the neighbor's side. According to his statement, it dampened the noise. However, the neighbor found it ugly and tore it down. Maybe there's an approach in that which you can follow up on?!
